Abstract:
An electronic timepiece with a solar cell is provided with a solar cell, a solar cell holding member, a light-transmissive character plate, a ground plate, and a ring-shaped calendar wheel. The solar cell includes a base material that is made of an insulating material, and a light-receiving unit that is arranged on a first surface of the base material. The solar cell holding member is fixedly attached to a second surface of the base material. The light-transmissive character plate is arranged on a timepiece front side of the solar cell. The ground plate is arranged on a back surface of the solar cell. The ring-shaped calendar wheel is disposed between the character plate and the ground plate. The solar cell holding member is arranged on a character plate side of the calendar wheel to position the calendar wheel.
